Poongsan has been producing a variety of copper and copper alloy plates, ranging from copper products for everyday life to high-tech industrial materials. These copper and copper alloy plates, which are recognized as high-quality materials at home and abroad, are representative industrial basic materials that are widely used in all industrial fields, including automobiles, electrical and electronics, semiconductors, communications, construction, and machinery. Poongsan has various casting facilities, including the world's largest shaft furnace, a hot mill capable of continuously rolling 6-ton slabs, a tandem mill, and a 20-stage cold rolling mill, as well as various hot and cold rolling facilities and heat treatment furnaces. We are building a large-scale integrated production system from the casting process to finishing processes such as cutting and packaging. Poongsan's rolled products are produced in various sizes depending on the type, ranging from 630mm in width, 0.03mm in thickness, and thickness tolerance to 2/1000mm. These products have accurate specifications and physical properties and a smooth surface thanks to the establishment of a thorough quality control system using cutting-edge inspection equipment. Excellent. Poongsan's copper and copper alloy rolled products are produced in a variety of ways, including pure copper, brass, phosphor bronze, nickel silver, cupronickel, and special alloy (PMC26 and other) depending on the alloy composition and casting method. In particular, in response to market demands for new high-strength copper alloys due to technological advancements such as the Internet of Things and electric vehicles, we have developed new alloys (P1000HS and others) and are applying them to high-tech products requested by customers.

Lumir is the first Korean company to successfully develop and manufacture this onboard equipment, delivering superior performance and significant cost savings compared to competitors’ products. By integrating non-volatile NAND flash devices into the image data handling unit, storage capacity has been significantly increased, with data retention maintained even when the power is off.The image data handling unit of the satellite is a core device that receives high-speed, large-capacity data output from Earth observation sensors mounted on the satellite—such as SAR or optical cameras—then compresses and stores the data in real time, while also performing encryption and encoding for transmission to ground stations. Lumir has successfully developed and manufactured this satellite-mounted device domestically in Korea for the first time, breaking reliance on imported technologies. This achievement secures Lumir’s competitiveness by delivering superior performance and significant cost savings compared to foreign products.
